Product Details

The Cometic C4127-120 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Jaguar 4.2L XK6 engines from 1973-1992. This high-performance gasket features advanced MLS construction that provides superior sealing and durability compared to traditional composite gaskets.

Key Specifications:

  • Bore Size: 3.690 inches
  • Compressed Thickness: .120 inches (120 thousandths)
  • Multi-Layer Steel (MLS) construction
  • Application: Jaguar 4.2L XK6 inline-six engines (1973-1992)

Features and Benefits:

  • MLS technology uses multiple layers of stainless steel with elastomeric coatings for maximum sealing capability
  • Handles extreme cylinder pressures and temperature cycling better than conventional gaskets
  • Accommodates minor surface imperfections while maintaining optimal sealing
  • Ideal for both stock and high-performance engine builds
  • Resists combustion gas leakage, coolant seepage, and oil contamination

Cometic Gaskets are manufactured in the USA using premium materials and are a trusted choice among engine builders and performance enthusiasts. The .120" thickness makes this gasket suitable for maintaining proper compression ratios in refreshed or modified XK6 engines.

Great

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
